y - x = 1.
or, y= 1+x
y - 2x = 3.
=>1+x -2x= 3 (substituting the value of y)
=>-x= 2
=>x= -2
y = -2+1 = -1
Therefore, x = -2 and y = -1
Given:
Consider the sides of the triangle are 4x+10, 2x-5 and 18 (in feet).
Perimeter of this triangle is to be no more than 77 feet.
To find:
The inequality and solution of the inequality.
Solution:
Perimeter of a triangle is the sum of all side.
Perimeter of given triangle
Perimeter of this triangle is to be no more than 77 feet. It means perimeter must be less than or equal to 77.
Divide both sides by 6.
Therefore, the required inequality is and the solution is .

Answer:
y=-2x-7
Step-by-step explanation:
just replace the m with what m equals (-2), and do the same thing with b (-7).
Answer:
